MACHINE FOR FIXING ooRos To TEXTILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 376,860, dated January 24, 1888.

Application filed November 11, 1886. Serial No. 218.556. (No model.)

To all whom it may concern:

Be it known that I, EMIL CORNELY, of

\Vashington city, in the District of Columbia,

articles to textile fabrics has been fully described, which consists in winding a thread around the cord and around the stitch of the seam by means of a revolving thread-carrier. The object of the present invention is to impart to said revolving thread-carrier an ascending motion while it passes over the cord and a descending motion while it passes its thread under the point of the needle-hook.

To understand fully this invention it must be remarked that the beauty of the work depends to a great extent upon the tightness of the seam to which the cord is secured, and when-said seam is made by means of a hookneedle said tightness-is obtained'by adjusting the needle in a veryclose position to the ma-- t-erial; but as therevolving threadcarrier must lay-its thread under the point of the needle its position must be a very low one for thisoper'ation, and when again it passes over the cord of a certain thickness its position must'be a higher one at that moment. It is therefore necessary that the revolving, thread carrier should have an ascending and a descending motion during its revolution. 7 I

Figures 1, 2, and 3represent the mechanism for producing said motion. Fig. 4 represents the mechanism for producingthe stitches, the

same as represented in Letters Patent No.

311,644 and with the same letters of reference.

- Fig. 5 representsthe passage of the cord or of a string of beads fromthe spool to the needlebar.

In Fig. 4, A represents the cloth; B, the needie-hook; G, its nipple; D, thenipple-tube; G, the revolving thread-carrier; H, the cord, which is represented asa bead-string upon which the beads are fixed in spaces;'I, the chain-stitch;-K, the thread of the revolving thread-carrier. I l l At Fig. 1 the revolvingthread-carrier G is b, so that the thread-carrier during its rota tion can be pressed lightly againstthe nipple O and its cording-guide a. The bearer F is not secured to the wheel W, but can freely slide within the guide L, which is secured to wheel 'W'. The wheel Wis turned by means of the mechanisms described in Letters Patent No. 262,742, of August 15, 1882. The bearer F is securedto its carrier F by means ofa spring,

also guided in itsvertical movement by means of the guide-rod d. A friction-roller, g, is secured to the bearer F and bears against a cam disk, M, which is secured upon the nipplev v tubeD. By meansoftheverticalupanddownward motion of the nipple=tube D and the pcculiar shapeof cam M, the bearer F, and consequently its th read carrier G, while revolving with the wheel W, arealternately raised and lowered at such moments of their revolution that they rise while passing over the co'rd, and that the spring 6 on rod d will press them downward when. the thread-carrier lays its resented in Fig. 4. o

Figs. 2 and 8 represent another arrangement. for the same purpose. The friction-rollerg is thread under the point of the needle, as repsecured tothe nipple-tube D. A cylindrical Y cam, O, is adjusted upon the tube N, and is presseddownwar'd against the roller 9 by the pressure of spring 1). The thread-carrier G v and its holder Fare secured to the cylinder O, and the holder F extends into a recess in wheel W, to participate inthe rotation of the latter. The up-and-down motion of the nipple-tube D and the peculiar shape of the cam on cylinder 0 cause the latter to rise and fall at the proper moment, as described above. It

is evident that in this arrangement, also,the cam may be secured to. the nipple-tube D, as represented in Fig. 1, and the friction-roller to the cylinder 0, to produce the same result. The thread is passed from the spool 9 through thread-carriers 2 and 3 into the take-up 4, and thence through'the guide 5 into the eye of the, thread-carrier G. v

In Fig. 5 I have represented an arrangement. for guiding the bead-string to the hollow needle-bar y, through which it passes downward;

through the central tube of the machine. V

beads are wound, and which turns on pin 10o represents the spool on which the stringed S, which is pivoted at b to the head-plate B.

When the needle-bar y is to be taken out of the machine, the lever S is turned aside, as

represented in dotted lines, 5, so as not to stand in the way of the needlebar. Z represents the head of the machine, to which the spool-holder w is secured.

For the sake of greater clearness I would observe that the bead-strings referred to consist of beads strung upon a thread and spaced or held the proper distance apart by means of a second thread. Such bead-strings have long been manufactured by means of an apparatus consisting of a spacer, by which the beads are automatically spaced or set the proper distance apart,va tube through which the string passes, and one or more revolving thread-carriers for winding the holding'thread.

It will be evident that the revolving threadcarrier having a rising-andfalling motion is applicable also to machines winding a thread around the chain-stitch, as described in Letters Patent No. 222,445, of June 8,1880, and No. 262,742, of August 15, 1882. When a thick thread is employed on the revolving thread-carrier, the cording-seam which is obtained will be so thick that the revolving threadcarrier must rise to pass over it, and it must again descend to lay the thread under the needle.

Having now fully described my said invention, what I claim is- 1. In a sewing or embroidering machine, the combination, with the stitch-forming mechanism, of the revolving thread-carrier and means for imparting thereto arising-and-falling motion in each revolution, substantially as described.

2. The combination, with the stitch-forming mechanism and the mechanism for laying a cord or like article on the fabric, of a threadcarrier for binding said cord to said seam by means of a second thread, and means, as specified, for lifting said carrier when passing over the cord and depressing it when laying its thread under the point of the needle, substantially as described.

3. The combinati0n,with sewing mechanism and cord-delivering mechanism, of the thread carrier, means for rotating the same,'a cam, and an anti-friction roller for raising and lowering said carrier at proper points in its revolution, substantially as described.

4. The combination, with the removable hollow needle-bar, of a guide-roller above the same and a pivoted support for said roller, whereby it may be moved to one side, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

EMIL CORNELY.
